Definition
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone
Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite

Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

Metapelite vs Granodiorite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Metapelite vs Granodiorite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Metapelite and Properties of Granodiorite. Learn more about Metapelite vs Granodiorite in the next section. The interior uses of Metapelite include Decorative aggregates and Interior decoration whereas the interior uses of Granodiorite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration and Stair treads. Due to some exceptional properties of Metapelite and Granodiorite, they have various applications in construction industry. The uses of Metapelite in construction industry include Cement manufacture, Construction aggregate, For road aggregate and that of Granodiorite include As dimension stone.
More about Metapelite and Granodiorite
Here you can know more about Metapelite and Granodiorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Granodiorite consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz and mineral content of Granodiorite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Metapelite vs Granodiorite, the texture, color and appearance plays an important role in determining the type of rock. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas, Granodiorite is available in black, grey, orange, pink, white colors. Appearance of Metapelite is Banded and that of Granodiorite is Veined or Pebbled. Properties of rock is another aspect for Metapelite vs Granodiorite. The hardness of Metapelite is 5-6 and that of Granodiorite is 6. The types of Metapelite are Not Available whereas types of Granodiorite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Metapelite is unknown while that of Granodiorite is white. The specific heat capacity of Metapelite is 0.72 kJ/Kg K and that of Granodiorite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Metapelite is heat resistant, impact resistant, pressure resistant whereas Granodiorite is heat resistant, wear resistant.
